the wagering requirement is high in my opinion. but what Doell achieved was not everyday scenario that someone can turn 8 bucks to 400 bucks. the blizz team should reconsider lowering their wagering requirements, at least an achievable one so players will be encouraged to play using their bonus. it is understandable to have high wagering requirements but if it is too high, then, it is just another way of saying you can't get out alive here... 
Coming out alive and taking bonuses from this new casino is likely to be difficult for anyone. I really will give up if I reach $400 but have to stay fully focused to complete 100%. Of course hope the wagering requirements are reduced so that we or anyone else can win like @Doell did. Because here we only want to review whether among the users who joined successfully made a withdrawal. For now the 1% Bilzz.io casino has managed to attract playing forum users. Maybe in the future it will be considered again as a continuous promotion.
